People >65 years: do not treat asymptomatic bacteriuria: it is common but is not associated with increased morbidity.

Catheter in situ: antibiotics will not eradicate bacteriuria; only treat if systemically unwell or pyelonephritis likely.

For antibiotic treatment of catheter UTI see pyleonephritis.

Do not use prophylactic antibiotics for catheter changes unless history of catheter-change associated UTI or trauma.
